Connectivity among subpopulations of Norwegian Coastal cod. Impacts of physical-biological factors during egg stages.
(The University of Bergen, 2012-04-19)
Norwegian Coastal cod form a stationary population of Atlantic cod ( Gadus morhua L.) consisting of several genetically separated subpopulations. A small-scale differen- tiation in marine populations with pelagic ...
Zooplankton abundance and distribution around on a seamount in the Andaman Sea, Thailand, measured with acoustic methods and biological sampling
(The University of Bergen, 2011-08-30)
Studies of abundance and distribution of zooplankton with acoustic instruments is new methodology in Thailand. In order to evaluate if the zooplankton could be detected and measured, a specific area around a seamount in ...
The value of size. Bioeconomic consequences of size-dependent pricing and fishing-induced evolution
(The University of Bergen, 2011-09-02)
The influence of fishing on the dynamics of fish stocks is a core element in
fisheries management. One of the most notable characteristics in this context is the sizestructure
of a fish stock, composed by the individual ...

(The University of Bergen, 2011-06-01)
During late summer and autumn 2008 the Norwegian Veterinary Institute Bergen received several diagnostic cases with similar histopathological changes. Due to unknown cause of the the condition it was subsequently called ...
Herring (Clupea harengus) in Lindåspollene before and during spawning: spatial decisions and school dynamics
(The University of Bergen, 2011-06-01)
Abstract
This study reports on the school dynamics of a self-sustained local population of Atlantic herring (Clupea
harengus) in Lindåspollene, south-western Norway, during pre-spawning and spawning, observed over a

Eksperimentell smitte av grønngylt, Symphodus melops, med V.tapetis - isolatene CECT 4600, LP2 og NRP45
(The University of Bergen, 2011-08-30)
The use of wrasse (Labridae) as cleanerfish in salmonid aquaculture is the only method for removal of salmon lice that does not have any negative impact on the environment. The use of wild-caught wrasse has increased during ...
Molecular characterisation of key components of the mucosal immune system in Atlantic salmon (Salmo salar L) and transcriptome analysis of responses against the salmon louse (Lepeophtheirus salmonis)
(The University of Bergen, 2012-04-17)
Mucosal immunity in mammals is mediated mainly by secretory immunoglobulin A (SIgA),
which is produced by IgA plasma cells commonly located in the lamina propria, and a
transport system involving the polymeric Ig receptor ...
Anaesthesia of farmed fish with special empasis on atlantic cod (Gadus morhua) and atlantic habibut (Hippoglossus hippoglossus)
(The University of Bergen, 2011-03-23)
During the life cycle as farmed animals there are numerous situations where fish are
subjected to handling and confinement. Netting, weighing, sorting, vaccination, transport and,
at the end, slaughter are common events ...
Characterization of the Atlantic cod (Gadus morhua L) eggs for estimation of spawning time and proportion of spawning females
(The University of Bergen, 2011-05-29)
A set of eggs from first time spawning Atlantic cod (Gadus morhua L) was investigated for the understanding of variations in egg sizes, e.g. with time in the spawning season, daily inter and intra variations, daily ...
Strategies for partition between reproductive investment and body growth in stationary and migratory stocks of Atlantic herring
(The University of Bergen, 2011-06-01)
The present study focused on the trade-off between reproductive investment and body growth of migratory and stationary Atlantic herring (Clupea harengus) populations. Published data from Norwegian spring-spawning (NSS) ...
